Hi,
This might sound weird, but is there a way to make drone create a new git tag every time a build is successful?
I saw a lot of tagging for the docker image, but was wondering if this can be possible

Note that if your repository is public, you will need to provide a way to authenticate the git+https push. This can be done creating a drone secret [1] that includes a username/password or oauth token that you can provide to the git command.

I saw a lot of tagging for the docker image

This tagging is being performed by a plugin, which is essentially just executing shell commands under the covers [2]. You could encapsulate the above shell commands in a plugin, if you really wanted.

Sorry, I’m not sure I understand the question, since Docker tagging and git tagging are separate things. If you want to push a git tag to your remote, I do not believe the Docker plugin is relevant here. The Docker plugin is used to build, tag and push Docker images to Dockerhub, which is a different use case.
